question 23

Multiple Choice

Let P ( t ) be the point on the unit circle U that corresponds to t. If P ( t ) has the coordinates $\left( \frac { 21 } { 29 } , \frac { 20 } { 29 } \right)$ , find $P ( t + \pi )$ , $P ( t - \pi )$ , $P ( - t )$ , $P ( - t - \pi )$ .

• A) \(P ( t + \pi ) = \left( - \frac { 21 } { 29 } , - \frac { 20 } { 29 } \right) , P ( \pi - t ) = \left( - \frac { 21 } { 29 } , - \frac { 20 } { 29 } \right)\) \(P ( - t ) = \left( \frac { 21 } { 29 } , - \frac { 20 } { 29 } \right) , P ( - t - \pi ) = \left( \frac { 21 } { 29 } , \frac { 20 } { 29 } \right)\)
• B) \(P ( t + \pi ) = \left( \frac { 21 } { 29 } , - \frac { 20 } { 29 } \right) , P ( \pi - t ) = \left( - \frac { 21 } { 29 } , - \frac { 20 } { 29 } \right)\) \(P ( - t ) = \left( \frac { 21 } { 29 } , - \frac { 20 } { 29 } \right) , P ( - t - \pi ) = \left( - \frac { 21 } { 29 } , \frac { 20 } { 29 } \right)\)
• C) \(P ( t + \pi ) = \left( - \frac { 21 } { 29 } , - \frac { 20 } { 29 } \right) , P ( \pi - t ) = \left( - \frac { 21 } { 29 } , \frac { 20 } { 29 } \right)\) \(P ( - t ) = \left( \frac { 21 } { 29 } , - \frac { 20 } { 29 } \right) , P ( - t - \pi ) = \left( - \frac { 21 } { 29 } , \frac { 20 } { 29 } \right)\)
• D) \(P ( t + \pi ) = \left( - \frac { 21 } { 29 } , - \frac { 20 } { 29 } \right) , P ( \pi - t ) = \left( \frac { 21 } { 29 } , - \frac { 20 } { 29 } \right)\) \(P ( - t ) = \left( \frac { 21 } { 29 } , - \frac { 20 } { 29 } \right) , P ( - t - \pi ) = \left( \frac { 21 } { 29 } , \frac { 20 } { 29 } \right)\)
• E) \(P ( t + \pi ) = \left( \frac { 21 } { 29 } , \frac { 20 } { 29 } \right) , P ( \pi - t ) = \left( - \frac { 21 } { 29 } , \frac { 20 } { 29 } \right)\) \(P ( - t ) = \left( \frac { 21 } { 29 } , - \frac { 20 } { 29 } \right) , P ( - t - \pi ) = \left( - \frac { 21 } { 29 } , \frac { 20 } { 29 } \right)\)
